hi Naresh,
brief answer - yes.
... but, where does the return current flow for your piece of wire?
This will affect the value for C because it is between your wire and a local
reference, which is also where your return current flows. The answer also
affects the L value - a "loop inductance" for SI applications.
With no local return path (reference) your C is "to infinity" and your L is
a "partial inductance". Neither of these abstract concepts are highly useful
for SI applications, though they are computationally meaningful for DC EM
solvers (but not for AC EM solvers) and multiple "partial" values can be
manipulated with circuit concepts to become applicable to SI applications.
cheers,
-Brad
